Depends on cause
If it is a diffuse goiter
, it may be caused by high tsh, which can arise in hypothyroidism
or iodine deficiency
(rare in usa, as salt is iodinated) or excessive goitrogens in susceptible ppl (like cauliflower).
Treating the hypothyroidism can slow growth, if the above is the cause. If enlarging modules is the cause, surgery. Depends on cause, radioactive
iodine may help.
